The Challenge
Automotive accessories Vendor Central account. Thin per-SKU margin meant standard scaling tactics (lift ACOS to drive volume) would destroy profitability. Brand needed volume expansion at flat ACOS — a structurally harder requirement than the typical 'pay more, sell more' play.
What the brand looked like before we engaged
Automotive accessories brand on Amazon Vendor Central. Catalog spans car care, interior accessories, lighting, electronics. Account was running at:
- Conversion rate: 3.12%
- CTR: 0.81%
- ACOS: 18.5%
- ROAS: 5.4x
- Ad sales: ₹1.65 Cr
- Orders: 29,200
Vendor Central margin profile means there’s no slack — every percentage point of ACOS matters. Volume growth had to come without ACOS expansion.
Exact action → exact result
Action 1: SKU-level economic analysis + cluster bidding
Every SKU mapped to its actual contribution margin (Vendor Central wholesale price minus Amazon fees, returns, ad allocation). SKUs grouped into 5 clusters: high-margin, low-margin, seasonal, declining, and launches. Each cluster got its own ACOS target.
Result: Conversion rate climbed from 3.12% → 3.6% (+15.4%) — bids concentrated on SKUs where the conversion economics actually worked.
Action 2: Vendor Central A+ content refresh
A+ content rebuilt across top 90 SKUs with technical use-case visuals + comparison tables (auto buyers want fitment + compatibility confirmed). A+ refresh drives CVR lift directly.
Result: Listing-level CVR improvements drove blended CVR 3.12% → 3.6%. Ad sales jumped ₹1.65 Cr → ₹1.91 Cr (+15.8%).
Action 3: ACOS-discipline bid system
ACOS was monitored hourly. Any keyword crossing 22% ACOS auto-paused for review; any keyword sub-12% ACOS auto-bid +15% within budget caps. No SKU was allowed to drift outside its cluster target band for more than 48 hours.
Result: Account-blended ACOS held at 18.5% → 18.8% — effectively flat — while volume grew 15.3%. The volume-without-margin-loss requirement was met.
Action 4: Festival + auto-season pre-loading
Two main seasonal windows in the automotive category (festive + monsoon-prep). Budget pre-loaded 14 days before each.
Result: Orders climbed from 29,200 → 33,664 (+15.3%). Seasonal months delivered the bulk of incremental volume.

What ATIL takes from the Automaze account
- Vendor Central economics demand cluster-level targets. A single account-wide ACOS target obscures the right strategy for thin-margin vs healthy-margin SKUs.
- Flat-ACOS growth is the hardest Amazon outcome to deliver. Volume + margin are usually trade-offs. Holding both requires SKU-level discipline, not portfolio-level optimisation.
- A+ refresh is the under-used CVR lever. Most Vendor Central accounts treat A+ as a one-time setup. Quarterly refreshes drive measurable CVR lift.
